The Quaternary glaciation, also known as the Pleistocene glaciation or the current ice age, is a series of glacial events separated by interglacial events during the Quaternary period from 2.58 Ma (million years ago) to present.
In popular culture, there is often reference to "the next ice age".[24] Technically, because Earth is already in an ice age at present, this usually refers to the next glacial period (because the Earth is currently in an interglacial period).
One can see glacial striations on rock formations in Jacksboro TEXAS.
That far south...
I just wish the reporters would get their terms straight.
An “inter-glacial” period is BETWEEN ice ages, which are also known as “glacial” periods due to stable or advancing glaciation.
We are not BOTH, in an “ice age” AND an inter-glacial period.
I believe we are at present in an “inter-glacial” period because glaciation is not advancing and it seems for way longer than the industrial age (and AGW “global warming”) has been retreating gradually, in fits and starts.
“I’ve read that Greenland was named the way it was because at the time that name was attached it was,in fact,green.”
No human has ever seen Greenland when it was ice free and all green.
The name Greenland was simply a marketing ploy to make it more attractive.
Ice Age:
An ice age is a period of long-term reduction in the temperature of Earth’s surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.
By this definition, we are in an interglacial period—the Holocene—of the ice age. The ice age began 2.6 million years ago at the start of the Pleistocene epoch, because the Greenland, Arctic, and Antarctic ice sheets still exist.[2]

We do have alpine glaciers, and ice caps... thus we are in an ice age.
until Antarctica becomes ice free, we are still in an ice age.
But Greenland at one time had a climate with a sufficient enough growing season to support Scandinavian style agriculture. That “warming period” came to an end roughly at the time of Columbus. (Probably before because roughly at the time of Columbus was when the Viking settlement was abandoned.)
Great post!
I always love to ask “Warmers” if the Holocene has ended and why they think so!
Seems to me that AlGore has succeeded in his goal to stop Global Warming.
Snowing at my place here in south central New Mexico, as I type this.
There is still agriculture in Greenland.
Of course, they are not growing bananas, but they do farm.
Yes I know I have been there.
But at the time “roughly of Columbus” agriculture collapsed due to cooling sufficiently to fail the colony.
Even if you use all caps, no one is listening.
Yes I’ve seen them.
Can you hear me now ?
Basically for the first two thirds of the Quaternary, the repeating ice age cycle worked on a 41,000 year period. The last third of the Quaternary the cycle period was 100,000 years. Doing the math gives us about 50 interglacial periods when the surviving apes froze their cajones off.
That is correct.
We are in the interstadial portion of the glacial cycle. That is the short warm period. The long cold period is called the interglacial.
